About FinanceBilldesk
Last updated: October 2026FinanceBilldesk is a small collection of free finance tools for U.S. freelancers, small business owners and households: an invoice generator, a 50/30/20 budget planner and calculators for loans, mortgages, compound interest, savings goals, sales tax and profit margin.
How the calculators work
Each calculator uses a standard financial formula, and every tool page shows that formula and a worked example so you can check the result yourself. Everything is calculated in your browser, so the numbers you enter are not uploaded or stored.
What these tools are not
The results are estimates for planning and education. They are not financial, tax or legal advice, and actual loan terms, taxes and investment returns depend on your lender, your location and the market. Talk to a licensed professional before making a major financial decision.
